Let's divide 649397 by 7
The aim is to understand the frequency of 7 in 649397.

Advancing to step 1:
6 divided by 7 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 7

Advancing to step 2:
If we divide 64 by 7, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 63 away from 64, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 7

On to step 3:
When dividing 19 by 7, we get 2 with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 92.0
The remainder is 5 after subtracting 14 from 19.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 7

Let's proceed to step 4:
7 can be fit into 53 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 927.0
Subtracting 49 from 53 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 7

Moving on to step 5:
When dividing 49 by 7, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 9277.0
The remainder is 0 after subtracting 49 from 49.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 7

On to step 6:
If we divide 7 by 7, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 92771.0
Subtracting 7 from 7 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
0 divided by 7 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 92771.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
7 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 92771.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 92771.0, and the remainder is 0.0.
